LINIE AND SEDIIVIENT EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 766,7 50, dated August 2, 1904. Application filed May 6, 1903. Serial No. 155,868. iNo model.)

To all whom it may concern:

v ration of the lime and sediment from the water is accomplished by delivering the water from the feedpipe into a device adapted to effect a partial purification thereof, and from thence the water is delivered to a second device, wherein it is further purified and from whence it is discharged into the boiler or other receptacle, the extracted sediment and lime being' conveyed away by means of a discharge-pipe.

My invention is particularly designed, therefore, to prevent foaming of the water in the boiler and the scaling thereof and tends to retain the boiler in a cleanly condition.

To this end my invention consists in certain novel features of construction and combinations of parts, such as will be more fully described hereinafter, and particularly pointed out in the claims.

The figure of the accompanying drawing is a side elevation of my improvements applied to a boiler', parts being' broken away.

A indicates a horizontally-disposedboiler to which my invention is connected. It is obvious, however, that the boiler may be either vertical or inclined without affecting the scope of the invention in the slightest particular. The boiler is provided with the usual steam-dome l.

The feed-water pipe is designated at F and extends from any suitable source to a casing E, with the upper end of which the pipe communicates by means of the elbow-union Gr and the short length Q. This purifying-casing comprises a body portion 3, preferably cylindrical and provided with annular' shoulders 4 4 at either end. A cap H is secured to the flange or shoulder at the upper end of the casing by means of bolts p p and is provided with a collar 5, secured around the short length Q. A base I is secured to the lower annular flange 4 in a manner similar to the means for securing the cap H and is also provided with a threaded collar Q in alinement with the collar of the cap and adapted to be secured upon the connecting-pipe L. This connecting-pipe L may extend upwardly through the collar Q, and some distance into the casing E and is adapted to support a series of purifying receptacles or funnels J J of gradual]y-increasing size and dimensions, the smallest of which is supported upon the closed upper end of the pipe L, the next largest below and separated a suitable distance therefrom, and so on, the largest receptacle being at the bottom. This arrangement, it will be observed, permits the periphery of the largest receptacle to extend laterally into a vertical plane beyond that occupied by the next largest of the series, and so on. The short length 2 may be provided with a spreader or sprayer for the water, and the pipe L is provided near its point of exit from the casing E with a plurality of apertures K, whereby communication between the interior of the casing and the interior of the pipe is maintained.

Located within and extending from end to end of the boiler is a separating-pipe B, the upper portion of which is provided with a series of apertures O O. The ends of the separating-pipe extend through suitably-packed bearings in the heads 6 6 of the boiler and are provided with caps O C, apertured to receive a rod I), which extends through the entire length of the se11 arating-pipe for securely retaining the pipe in position and serving as an additional support therefor. The ends of the rod D are provided with adjusting-nuts 7 7 for retaining the caps tightly in place.

The separating-pipe extends through the steam-space of the boiler at a suitable distance above the water-line NV.

The connecting-pipe L communicates with the separating-pipe B, as does a sedimentpipe M, provided with a valve N, whereby the lime, sediment, and other impurities extracted from the water may be washed out of the casing and separating-pipe and conveyed away.

The operation is as follows: The water is admitted to the casing E through the feedpipe F and is discharged thereby into the rst of the purifying funnels or receptacles J, which soon overflows, permitting' the surplus water to fall over its edge into the next largest receptacle below and in like manner tothe next until from the lowest and largest receptacle it falls to the base I of the casing E, and when the water has acquired a suflicient depth it -overiiows into the pipe L through apertures K, located a little distance above the base I. This continuous overflow permits the impurities to settle in the pans or receptacles J and also on the base I, so that the partiallypurified water is conveyed by the pipe L to the separating-pipe B, wherein the impurities are further extracted, and through the perforations O O of which pipe the water is discharged into the boiler, the feed-pipe, the casing, and separating-pipe,together with the sediment-pipe, being under boiler-pressure,

and the water passes through the steam in the separator-pipe and casing, whereby the adhesive quality of the lime is neutralized and the lime and impurities caused to settle in the sedimentpipe M. The heavier impurities will settle in the receptacles J J and in the bottom of the separating-pipe B, from whence they may be washed into the sediment-pipe M when the valve N has been opened.

It will be observed that instead of utilizing the entire device as shown either the casing and its connected parts or the separating-pipe may be used independently of the other, but with a less degree of efliciency. It will further be observed that many changes might be made in the form and arrangement of the parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction set forth; but,

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a boiler, of a purier comprising a casing, a pipe'communicating with the upper portion thereof, a conveyer-pipe to which the casing is secured, the con veyer-pipe extending thereinto, a series of separating-receptacles secured upon the conveyer-pipe within the casing, a perforated separating-pipe, the ends of which are received in and project through the heads of the boiler, the conveyer-pipe communicating with the separator-pipe at one of its projecting en s.

2. The combination with a boiler, of a purii'ier comprising a casing, a feed-pipe communicating with the upper end thereof, a conveyer-pipe to which the casing is secured and by whichit is supported, a series of separating-pans secured to the conveyer-pipe within the casing, and a perforated separator-pipe located in the boiler, the conveyer-pipe extending to and communicating with the separator-pipe.

3. The combination with a boiler, of a water-purifier comprising a casing, a perforated conveyer-pipe leading from the boiler and projecting into the casing, a plurality of sediment-collectors supported upon the conveyerpipe and means for feeding water to the uppermost collector.

4. The combination with a boiler, of a wa` ter-purifier comprising a casing, a feed-water pipe communicating with the upper portion thereof, a conveyer-pipe projecting into the casing from the lower portion thereof, an apertured separating-pipe located within the boiler, the conveyer pipe communicating therewith and a series of separating-receptacles located within the casing, the conveyerpipe provided with apertures formed in that portion within the casing.

5. The combination with a boiler, of a water-purifier comprising a casing, a series of separating-pans located therein, means connected with the upper portion of the casing for supplying water thereto, means connected with the lower portion of the casing for supplying steam thereto, an apertured separatingpipe located in the boiler, the steam-conveying means connecting the casing and separating-pipe, the casing and separator-pipeoperating under boiler-pressure.

6.
